The floppy disk, which has been around since the early days of home computing, is finally being killed off by Sony. The Japanese electronics manufacturer, which last year sold well over 12 million of the devices, has announced it will stop making floppy disks next year, leaving no serious manufacturer in the market place.The decision is the final nail in the coffin for floppies, which since they were first developed in 1971 have helped consumers store documents, pictures and data on an easy to use format.However, in recent years, the limited storage on most floppies compared with how much data can be stored on a CD or a USB memory stick has meant they have become increasingly obsolete.The most recent floppy disks have a maximum storage capacity of 2 megabytes though most had less. This compared with the 4 or even 8 gigabytes consumers can now buy on a standard USB stick – 2,000 or 4,000 times the size of the largest floppy.
